運行以下查詢時出現「遇到零分錯誤」錯誤

我不確定錯誤，因爲我試圖運行此查詢。它給我零分錯誤。此錯誤發生在第1行。運行以下查詢時出現「遇到零分錯誤」錯誤

Msg 8134, Level 16, State 1, Line 1 
Divide by zero error encountered.

任何人都可以請幫忙嗎？

請不要使用不適用於您的問題 –

標籤這是不可能沒有回答實際數據。但是，您發生的部門數量很多，所以這就是問題發生的地方。試着做一個CASE語句，如果分母是0，那麼輸出NULL –

這裏只有一個商可以失敗 - 有查詢3個師，2除以常數。試試這個：

SELECT temp1.*,90 as Plan_val,max(cast(Round(temp2.actual,0) as int)) as actual_val FROM(
SELECT t.[Problem_Type_Name(Parent)],t.[Problem_Type_Name(Child)] , REPORT_DATE, CLOSE_DATE,[Assigned Tech],NAME , Job_ticket_id FROM (
SELECT 'NOC Incident Resolution - High' as [Problem_Type_Name(Parent)],[Problem_Type_Name(Child)] , REPORT_DATE, CLOSE_DATE,[Assigned Tech],NAME , Job_ticket_id 
FROM TEMP_TICKET_STATE 

UNION 

SELECT 'NOC Incident Resolution - High' as [Problem_Type_Name(Parent)],[Problem_Type_Name(Child)] , REPORT_DATE, CLOSE_DATE,[Assigned Tech],NAME , Job_ticket_id 
FROM TEMP_TICKET_STATE 
where [Problem_Type_Name(Parent)]='Incident (Technical Issues)' and PRIORITY_TYPE_NAME in ('High') AND (ISNULL([Escalated to Closed time],0) <= 120 or ISNULL([Escalated to Resolved time],0) <=120)) t 

group by t.[Problem_Type_Name(Parent)] ,t.[Problem_Type_Name(Child)] , REPORT_DATE, CLOSE_DATE,[Assigned Tech],NAME , Job_ticket_id) temp1 

INNER JOIN 

(
SELECT t.[Problem_Type_Name(Parent)],t.[Problem_Type_Name(Child)],0 AS plan_val, 
    -- CHANGE IS THE CASE ON THE NEXT LINE! 
    case when sum(t.Total_tickets) = 0 then null else cast(Round((cast(sum(t.Total_tickets) as decimal(38,2))- cast(sum(t.Alarm_Val) as decimal(38,2)))/cast(sum(t.Total_tickets) as decimal(38,2))*100,0) as int) end as actual FROM (
SELECT 'NOC Incident Resolution - High' as [Problem_Type_Name(Parent)] ,[Problem_Type_Name(Child)],0 as Alarm_Val, cast (count(distinct [Job_ticket_id])/4 as int) as Total_tickets 
FROM TEMP_TICKET_STATE_month 
group by [Problem_Type_Name(Parent)] ,[Problem_Type_Name(Child)] 

UNION 

SELECT 'NOC Incident Resolution - High' as [Problem_Type_Name(Parent)] ,[Problem_Type_Name(Child)],cast (count(distinct [Job_ticket_id])/4 as int) as Alarm_Val, 0 as Total_tickets 
FROM TEMP_TICKET_STATE_month

這給了我以下錯誤：Msg 102，Level 15，State 1，Line 30 'temp2'附近的語法不正確。 – Kirk1993

@SankW - 對不起，還有一個編輯還在......幾條線從底部切下。 –

謝謝Max。這工作。 – Kirk1993

據我所知，唯一的分母可能是零。其他似乎是用於捕集可怕被零除恆定4.

一種簡單的技術是NULLIF（）。

例如NullIf(<any denominator>,0)這將返回NULL，如果分母= 0，你的情況

所以：

NullIf(cast(sum(t.Total_tickets) as decimal(38,2)),0)
